Hi,

Is there a clean way to match on an email address the way procmail ^TO_ did? that was a macro which expanded to (^((Original-)?(Resent-)?(To|Cc|Bcc)|(X-Envelope |Apparently(-Resent)?)-To):(.*[^-a-zA-Z0-9_.])?)

so you could write

• ^TO_dovecot dovecot

and grab messages to the list. In sieve, I find myseld writing ["To","cc"] and wonder if there's a better way. You could use the X-BeenThere or List-Id headers to match mailing list traffic

I’ve been using:

if header :contains ["List-Id","Mailing-List", "Sender","X-List-Name","List-Post"] ["mailto:php-general@lists.php.net"] { fileinto "lists/php/general"; stop; }

For all my mailing list traffic. That seems(!) to catch most of them.

I can't remember where I got the original algorithm (and, in particular, the ordering) from, but I've been using the attached sieve script for a while with numerous mailinglists. It uses the 'regex' module to parse the mailing-list name from the headers (with various attempts to handle most of the major mailing-list applications). The listname is lower-cased (for consistency) and the message is filed into that folder (creating the folder if necessary). This means that, when I sign up for a new mailing-list, messages just start appearing in their own folder.
